Deuteronomy 31:1-6 YLT

1 And Moses goeth and speaketh these words unto all Israel,
2 and he saith unto them, `A son of a hundred and twenty years [am] I to-day; I am not able any more to go out and to come in, and Jehovah hath said unto me, Thou dost not pass over this Jordan,
3 `Jehovah thy God He is passing over before thee, He doth destroy these nations from before thee, and thou hast possessed them; Joshua -- he is passing over before thee as Jehovah hath spoken,
4 and Jehovah hath done to them as he hath done to Sihon and to Og, kings of the Amorite, and to their land, whom He destroyed.
5 And Jehovah hath given them before your face, and ye have done to them according to all the command which I have commanded you;
6 be strong and courageous, fear not, nor be terrified because of them, for Jehovah thy God [is] He who is going with thee; He doth not fail thee nor forsake thee.'
